Write how your protagonist and their best friend or their closest ally met. Did they become friends immediately? Did they dislike each other at first? Were they forced into working with each other? Were they old school friends? Is your protagonist’s best friend imaginary? Are they the protagonist’s pet, or an animal of some kind?
This is one of the sections that I’ll be addressing! Getting To Know Your Characters is a series of ideas I’ve come up with to help you find out about your characters. Just like real people, characters are complex beings, and can’t be defined by one simple trait. Throughout a novel, characters change, just as people change.
